.To a/ZZ whom t may concern/.f

Beit known that I, KARL ScHAAL, a citizen of the United States, residing at Seward,

in the county' of Seward. and State of Ne-` braska, have invented new anduseful lmprovements in Harrow Attachments for` Sulky-Plows, of which the following is a speciiication. This invention relates to harrow attachments for plows; and it has particular reference to anv improved harrow attachment adapted to be applied to and used in connection with sulky-plows or riding-plows of ordinary construction.

a manner as to operate upon the furrowventiionis better understood, the samecofn-v sist's' inthe improved' constructiong'- arrangelarly'poii'ted "outin the' claims. f f In"the'accompanyingdrawings-:has been One obj ect of the invention is to provide a simple and, efficient harrow .attachment which may be'readily applied or attached to the frame of an ordinary sulky-plow in such slice immediately behind the 'turning-plow, so' as to break up the clods andpulverize the -soil while the latter is yet comparatively moist and before it becomes baked and caked by exposure to the sunL and air, another important advantage being thatjby the improved attachment I am enabled to perform .at a single operation the'plowing and harrowing which have heretofore usually required going over the groundV twice in the performance. Another lobject of the invention `is to provide improved means for supporting yand adjusting' the harrow attachment.

f Further objects" of tlie 'invention' are to `simplify and: improve the vconstruction an operation of this class of devices.

With these and other ends in view, `which will 'readily appear as lthe naturev ofthe' l inment, "and combinationE of parts, which' 'will loek hereinafter fully' described", and articul i l shown a) simple and preferred form'ofthe invention, it being, howeverfunderst'ood that no limitationis necessarily' made tothe p reoise structural detailstherein exhibited, but

\ that changes, alterations, and 'modifications sorted to when desired. f

tubular harrow-bars. Fig. 7 is a perspective lp ossessing the requisites of lightness strength,

and general efliciency to operate upon' the Figs. 10, l1, and'. l2

soil. As the harrow is usually intended t'o operate upon a single furrow slicefonly, it need not be large. In the drawings-has been shown fa harrow composed of." a plurality" of tubular bars l 1, having teeth or spikes y2"2 and provided with upward-extending' arms 3 4, connected pivotallywith longitudinal bars 5, which may be regarded as constitutingthe harrow-frame. The upper ends of the arms 3, which lattervare'long'er than the arms 4, are pivotally connected by a link-bar 6, .v

carryinga segment-rack 7. A leverS, pivotally connected-with the 'link-bar 6 and' with the adjacenty harrowbar 5, is provided'with 'a stop member 9 adapted for engagementwith thexrackl for the purpose of 'retaining' the parts controlled-thereby` in position' vwh'eri adjusted; It will be seen 'that bythissimple mechanism the teeth orI spikes of the harrow maybe adjusted to4 anfdifsecuredinposition at various'inclination'sfand` 'also that the toothed `harrow-bars'maybel rocked or oscillated in order to effect `the discharge there'- from ofany `trash'accumulated thereby. lTwo of the tubular'spiked harrow-bars', one

provided with sleeves 'or clips 10 fin which they may turn freely and which provided with upward'extensions 1l for theIpa'ssag'e of a rod oibolt vl2, upon the front erid f'wliich ICO of which is the front bar ofv the harrow, are

` `bar 2.0, lwhich is secured upon the l'plate or 16 represents anangular plate or bracket which is suitably bolted or otherwise-secured upon the frame F of an ordinary riding-plow P, 'which maylbe of any desired construction. i

The :angular zplate lor -bracket 16 rhas f an yupward-'extendinglug `17, upon which ispivoted a :lever 218, having :a stop lmember 19, adapted lfor engagement with a'eurved rackbracket, Ethe 7stop Amember being guided through :sleeves or guides V21, lwhereby it is bracedand reinforced.

Thefrodor'bolt 12 ofthe harrowisoonnected v'with yI the yplate'v or bracket `16 by means of frontand rear arms :A'and 1B, the former of which ,is a stiff frigid'arm orI connecting member, while'thelatter, B, is a compound arm composedofithree members or'sections 22, 23, and 24. One end of the section22 is bolted 'upon'the-angle plate or'braeket 1G, and the opposite 'end 'of said `section vcarries a hinge 4mem'ber or xcasting .25, having -apertured'lugs 26 'forfthe'reception =betwee1rtliem of the inner end=of the section 23, which lhas an -eye -27 for Ithe passage of `an vapproximately lverticalpivotjpin or pintle 28, `upon which lthe section 23 maylswing in an approximately Ahorizontal plane. The outermost-section 24 :issecured at 'its outer end upon the rod or bolt 12,\andat its opposite end Litcarries a 4:plate'or .casting Y29, vprovided with flanged rollers l30, between which the outer endof the seetion-23 is slidablymount- \ed,-said-section.23ibeing provided' at its outer extremity 'withfar cross-piece 31 to prevent it from escaping from between the .guide-'rollers30` The casting 4'or hinge -member A25 is 'provided with a laterally-extending sleeve 32, disposed in yline 'with an'aperture33 in the section 22 lof lthelarm LB. Firmly bolted or otherwisesecureduponithe arm A'is a flanged 'plate orcasting 34, having a laterally-extendingIslee'ved35, which'is disposed in fregistry with aperfora'tion of thesaidfarnr `A=bolt or \connecting ymember 36 lextends 'through the arms A and -B and througlrthe sleeves 35 and-32 ofthe castings connected tosaid arms,

`and upon said bolt, `between fthe sleeve "35 and ther arm B,thereis also mounteda spacing-sleevey 37 for @the purpose 1 of keeping the ipartsproperly spaced apart.

' 'The lever 18, which isused forthe purpose \of adjusting the harrow andforretaining the same inyadj usted position, yis connected with thebolt 36 bymeans of extension-members S, each of whichislcomposed of a pair of rods- `hooks 42 43.

38 land 39, having terminal eyes 40 41 at the ends, which are connected, respectively, with the lever 18 and with the bolt 36 and provided at their opposite ends with terminal Said rods are also provided near the ends having the eyes 40 41 with cross-bars 44 45. vrl`he rods 38 39 are placed in juxtaposition, and springs 46 are coiled upon said rods between the hooked ends and the cross-bars of the latter. It will thus be seen that the rods 38 39 are slidably connected with each other in suoha manner that the springs S will lbe tensionedfeither by extending the rods or bycollapsing the same. By this construction itwill `be seen that when the adjusting-lever is -manipulated to raise the arms A 'B,so as to llift 'the harrow from the ground, the said harrow will be resiliently supported and will ride easily and without jarring, when, on the other hand, the harrow is moved in adownward direction to foree the teeth or spikes into the'ground it will be subject to pressure/by the springs S, whereby the teeth or spikes will `be held resiliently in engagement with the ground. This is an important feature ofthe invention, since by this `construction the harrow may be subjected to any desired `pressure vfor the purpose of causing the teeth to enter the desired distance into the soil, :and at the same time if obstructions `should `be encountered. the harrow is capable-of rising, so as to rdeover such obstructions without dangerof breakage.

Suitably connectedwith-the front harrowbar 1, nearthe inner end of'saidbar, is a rod 47, having an eye 48 engaging `the .harrowbar, from which the said rod extends in an upward direction. The upper end of said rod is confined Ainan'eyebolt 49, y'connected with the arm A. The object of this rod is simply Lto keep the harrow from tilting or toppling over lwhen it -is raised Afrom `the ground. lt is obvious that 'this rod may also be utilized for the purpose ofsecuringthe harrow in` a` somewhat-inclined position if for any reason it should be found desirable to do so.

AAdraft-bar or `connecting member 5()l is suitably secured to one side of the plowframe F, and the rearend ofsaid draft-baris extended '(lownwardly, as shown at 51, and

`is connected, as by means of a pin or bolt 52,

with the clevis 15 at the-front end of theharrow. This member not only constitutes a draw-bar, but italso'serves to prevent the harrowvfrom crowding in a forward direction and to retain it inthe desired position.

From the foregoing description, `taken in Vconnection with the drawings hereto annexed, the'operation and advantages of thls nivelltion will be readily understood by those skilled inthe art towhich it appertains.

`It is obviously desired to harrowthe soil in order to break the clods and pulverize the ICO IIO

zol

dirt at the( earliest`A moment possible after l plowing, especially in arid sections, where, the soilthat is turned by the process of plowing is apt to become quickly caked to a hard condition, where it is difficult to break and pulverize it successfully.

By the present invention means are provided for harrowing, so as to break and pulverize the soilsimultaneously ,with plowing, ande the harrow of the present invention is constructed and attached to the riding-plow in such a manner that the strain upon lthe team will not be materially increased.

The harrow attachment may be very easily and conveniently adjusted so as to cause the teeth or spikes to enter the desired distance into the soil, and the harrow attachment may be likewise very easily elevated from the ground and supported in a raised and inoperative position. When the plow is turned at the corners of the field or at the ends of the furrow, the sections 23 and 24 of the arms B will collapse, so that the plow may be turned prior to the turning of the harrow, this movement being made possible by the presence of the hinge-joint which connects the sections 22 and 23 of the said arm B. When the plow has been turned and moves again in a forward direction, the strain exercised by the draft-bar 50 will serve to swingthe harrow around to the proper position for movement in a forward direction.

It is obvious that the connections between the various parts of the device for instance, the connections of the arms A and B with the boltl 12- should be sufliciently loose to enable' the-parts to move and operate freely in the manner and for the pnrpose described.

I desire it to be understood that in the practical manufacture of this apparatus I do not regard myself aslimited to the precise construction herein` described, inasmuch as many departures from said construction may be made within the scope of the invention.
